Ivinci motors12/21/2023 ![]() ![]() The engine has been extremely successful and reliable, with more than 200 built. ![]() The HM7 engine it will replace has been in service since 1979, on the Ariane 1 through 4 rockets in increasingly powerful variants and, in its current HM7B version, on Ariane 5. That upper stage will be an adapted version of the Ariane 5 ME upper stage, equipped with the Snecma Vinci engine and specific propellant tanks. The ME variant will also bridge the gap to Ariane 6, which will look to reduce costs, and increase flexibility, by replacing Ariane 5's cryogenic main stages with a modular, solid-fuel first and second stage configuration topped by a re-ignitable cryogenic fuel upper stage. Ariane 5ME, being readied to fly from 2017 or 2018, will boost payload by 20% to 12T compared to the current launcher. The test series of this fifth variant of the Vinci engine, named M5, will run for ten months and include 16 firing tests, to freeze the design by the end of 2014. Snecma is claiming a “complete success” on its first two test of its re-ignitable Vinci cryogenic upper stage engine under development for the European Space Agency’s Ariane 5 Midlife Evolution (ME) and all-new Ariane 6 launchers.
